To all inborn-it may-concern I I Be it-known that'l, LnRsOnRIsrIA NIEL- 'sE a-subj'ect of the King of Denmark, residi'ngat Copenhagen, in the Kingdom of Den lnaik, have invented certain new and useful Improvements in Lubricators; and I do declarethe' following to bee full, clear, and ex act'des'cription of the invention, such as will enable others skilled in theart to which it appertains to make and-use the same, reference being had to the accompanying drawings, and

My invention hasrelation to that class of 111 bricatorsadaptedtoinject oil into portions of machineryjinto which the oil can not enter by it s ownfgravity, on account of a counter-press V j 25, aure, by means of'a pump; and it consists in the indicates the reservoir containing the lubriimproved construction and combination of parts of such an injector-lubricator, as hereinafter more fully described and claimed.

In the accompanying drawings, theletter A cant, the lower end of which is secured into the top'ofa'rectangu-lar casing, B, having a removable front plate, 0; andlforming bearings .for ashaft, D,which-linay be revolved by any suitable.connectioiljwith thenloving parts of the engine towhichit'ns attached, the shaft be fi'ng in this instance provided with aratchetwheel, E, preventedfrom revolving'back 'by a pawl, F, pivoted upon the front plate of the casing and receivingmotion from a pawl, G, pivoted-upon a lever, H, hinged at its' inner' end upon the end "of the shaft. and receiving a verticalrocking motion fromthe machineryto which itji's connected in any suitable manner,

The shaftis provided with an eccentric disk,

I, which r'evolvesin ajslot, J, in a downward lyprojectin'gqlug, vK, ofv a bifurcatedl'frame, L,

' which reciprocates, resting upon its under sid e in the casingiand a piston, M, is securedto one,

voir, while the other,S, passes out through the fu'rcated frame, which piston reciprocates with rear plates of the casing,and with its upper side perforation or channel may be brought to register with twoperiora'tions, or channels, R and S, the one B of which is curved upward and connects with the outletof the lubricant-reserrear side of the casing connecting with the ma chine portion to belubricated, B being the inlet and S the outlet channel. The other up-' weirdly-projecting arm, T, of the bifurcated frame has a set-screw, U, passing through it,

the inner end of-which screw is adapted to strike the end of the pump, It will now be seen that as the shaft with its eccentric is revolved, the bifurcated frame will be reciprocated, and by taking the position shown in Figs. 2 and 3 ,of the pump, and supposing the frameto be moving in the direction of the arrow in the said figures, it will be seen that the piston will be drawn out of the pump, the latter being held from sliding with the piston by the adhesion of the sides of the pump to the sides of the.casing,which clamp the pump in sucha manner that it onlyslides bya stronger pressure, As the piston thus is drawn 'out, it will draw the lubricant from its reservoirfintothe' pump-bore through the inlet-channel, and in traveling out in the direction of the arrow the set-screw upon theother arm of: the frame willv strike the end of the pump,push1ngit outin the 90 direction of thearrow, placing the lateral channel of the pump opposite to the outlet' cha'nnel in the rear side'of the casing, whereupon the, frame will travel back in the direction opposite to'the arrow, pushing the piston into the pump, 9 which will-now'eject the lubricant through the outlet-chahnel into the parts to be lubricated;

whereupon the same motions and the same op eration will take place again, and 'soforth.

f The quantity of lubricantejected by the ap- 0 N, of the upwardly-projectingarmsoi the biq p 55 against the topplate'of the casin'g,and with its under side upon a plate or bearing, P, in the casing. The pump has a lateral perforation,

- Q, passing from the inner bore of the same out -to the rear side plate of the casing, and this paratus may be regulated either-by adjusting.

the speed, of the shaft and eccentric, or,' if

still finer adjustment is desired, by means of the I set-screw, which, it will be seen, will regulate the stroke of the pump by being moved 'i'art'her' in or out.

Having ;thus-described-rny invention, I claim and desire to secure by Letterslfatent' of the United States 1. Thecombination, in alubrieator, of a casing having an inlet and outlet channel" opening in the same plane, a pump havinga lateral ap- :GlilllIG from-Tits bore and reciprocatingin p plane so as to bring the aperture to register with the inlet andoutlet channeL-apiston reoiproeating inthe pn. mp,'an d means for recip:
